Abstract

"SISTEMA DE ANTENA PARA SISTEMAS DE COMUNICAçõES DE BANDA ESTREITA E MéTODO DE OPERAçãO". é revelada uma estação base aperfeiçoada para comunicação com unidades de comunicação em um sistema de troca de mensagens sem fio. De acordo com uma modalidade vantajosa, a estação base compreende: 1) um transmissor que é capaz de transmitir mensagens para as unidades de comunicação em um canal de envio, tendo uma primeira faixa de freq³ências; 2) um receptor que é capaz de receber mensagens a partir das unidades de comunicação em um canal reverso, tendo uma segunda faixa de freq³ências; e 3) uma antena que é capaz de transmitir as mensagens de canal de envio em um primeiro ângulo descendente elétrico abaixo do horizonte e de receber as mensagens de canal reverso em um segundo ângulo de inclinação elétrica descendente, em que o segundo ângulo é menor do que o primeiro.
